Background
The UV glue is generally referred to as shadowless glue (UV glue) which is also called photosensitive glue or ultraviolet light curing glue, and shadowless glue is a kind of adhesive which can be cured only by ultraviolet light irradiation, and can be used as an adhesive and can also be used as a glue material of paint, coating, ink and the like. UV is an abbreviation for Ultraviolet Rays, the term UV light. The Ultraviolet (UV) is invisible to naked eyes, is a section of electromagnetic radiation except visible light, and has a wavelength of 10-400 nm. The principle of shadowless glue curing is that a photoinitiator (or photosensitizer) in a UV curing material generates active free radicals or cations after absorbing ultraviolet light under the irradiation of ultraviolet rays, and the polymerization and crosslinking chemical reaction of monomers are initiated, so that the adhesive is converted from a liquid state to a solid state within a few seconds.
In the mobile phone industry, the traditional screen glue generally needs 12-24 hours to be completely solidified, which is very low for the assembly production efficiency of the screen; and whether or not solidification is possible to confirm accurately; therefore, in order to increase the setting time of the glue, it is necessary to use a color-changing UV glue which can facilitate rapid setting, so as to facilitate the bonding of the screen to the screen support and to check whether the UV has set.
